  2. Electrocardiography - Wikipedia

    en.wikipedia.org/wiki/Electrocardiography

    Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [ 5 ] using electrodes placed on the skin.

  3. Automated ECG interpretation - Wikipedia

    en.wikipedia.org/wiki/Automated_ECG_interpretation

    Automated ECG interpretation is the use of artificial intelligence and pattern recognition software and knowledge bases to carry out automatically the interpretation, test reporting, and computer-aided diagnosis of electrocardiogram tracings obtained usually from a patient.

    English: This image shows three sample biosignals: (1) A lead I electrocardiography (ECG) signal; (2) A fingertip photoplethysmography (PPG) signal; (3) A respiration impedance plethysmography (RIP) signal; Amplitudes are in arbitrary units.

    The 2018 European Society of Cardiology/American College of Cardiology Foundation/American Heart Association/World Health Federation Universal Definition of Myocardial Infarction for the ECG diagnosis of the ST segment elevation type of acute myocardial infarction require new ST elevation at J point of at least 1mm (0.1 mV) in two contiguous leads with the cut-points: ≥1 mm in all leads ...

  6. Rapid Interpretation of EKG's - Wikipedia

    en.wikipedia.org/wiki/Rapid_Interpretation_of_EKG's

    Rapid Interpretation of EKG's is a best-selling textbook for over 30 years [1] that teaches the basics of interpreting electrocardiograms. It adopts a simplistic fill-in-the-blank style [ 2 ] and is suited for medical students and junior residents. [ 1 ]

  7. Cardiac monitoring - Wikipedia

    en.wikipedia.org/wiki/Cardiac_monitoring

    An example of automatic monitoring is the transtelephonic cardiac event monitor. This monitor contacts ECG technicians, via telephone, on a regular basis, transmitting ECG rhythms for ongoing monitoring. The transtelephonic cardiac event monitor can normally store approximately five "cardiac events" usually lasting 30–60 seconds.

  8. Right axis deviation - Wikipedia

    en.wikipedia.org/wiki/Right_axis_deviation

    Bifascicular block is a combination of right bundle branch block and either left anterior fascicular block or left posterior fascicular block. Conduction to the ventricle would therefore be via the remaining fascicle. The ECG will show typical features of RBBB plus either left or right axis deviation. [7] [8]

  9. QT interval - Wikipedia

    en.wikipedia.org/wiki/QT_interval

    The QT interval is a measurement made on an electrocardiogram used to assess some of the electrical properties of the heart.It is calculated as the time from the start of the Q wave to the end of the T wave, and approximates to the time taken from when the cardiac ventricles start to contract to when they finish relaxing.
